SVG
SVG (Scalable Vector Graphics) is an XML-based vector image format for defining two-dimensional graphics, allowing images to scale infinitely without losing quality. It is widely used for icons, logos, charts, and interactive web graphics, supporting animations and interactivity through CSS and JavaScript. SVG files are text-based, making them editable with code and accessible for screen readers.
Developers should learn SVG for creating resolution-independent graphics that perform well on responsive websites and high-DPI displays, as it reduces HTTP requests compared to raster images and enables dynamic manipulation. It is essential for data visualizations, UI components, and animations in modern web development, particularly in frameworks like React and Vue where SVG can be integrated as components.
